Greetings all,

I’m a newbie in using Trelis.

I’d like to mesh a sphere using triangles quadratic with six nodes interpolated by quadratic functions. I have read and searched the manual for a long time. Maybe it is the ‘tri6’ but I don’t know how to use it correctly.

I can mesh a sphere using plane triangles and here is my script:

########################################################

new

set default element tri

create sphere radius 0.45

surface 1 size 0.1

mesh surface 1

disassociate mesh from volume 1

delete volume 1

########################################################

Does anyone know how to mesh a sphere by quadratic triangles?

I really appreciate you can help me to figure out this problem.

THANK YOU!!!
